About EDF Energy and Utility Warehouse
Who is EDF Energy?
EDF Energy is owned by the French state-owned EDF Group and is one of the UK's largest energy suppliers. It generates a large amount of electricity and supplies gas and electricity to UK homes. A key feature of the company is its role as a major power generator, running nuclear power stations and wind farms across the country. It also partners with Pod Point to offer home electric vehicle chargers.
Who is Utility Warehouse?
Utility Warehouse is owned by Telecom Plus PLC and is one of the UK's largest independent energy suppliers. It is a multi-utility provider that bundles energy with broadband, mobile phone contracts, and home cover. Customers get cheaper energy rates when they take out more services. It also offers a cashback card that lets customers earn money off their utility bills when they shop at certain stores.

Hi, I'm Rob, and I run Energy-Review.co.uk. I initially started this project in 2018 when I was looking to switch energy suppliers and found there wasn't a website that provided simple, data-backed reviews on all the suppliers available. Since then, I have spent a lot of time (too much, some may say!) looking at all publicly available data about each supplier and writing reviews using this information. These reviews are updated as regularly as possible, and any data is backed up by a source where necessary. I have also started writing guides on various energy-related topics, which hopefully you will find useful. If you find any issues, please use our contact form to let us know.
